OBJECTIVES: To evaluate the impact of HBV infection on pre- and postpartum health-related quality of life (HRQoL) in pregnant women. METHODS: A prospective matched cohort consisting of 70 HBV-infected and 70 healthy pregnant women was recruited from the Fifth Affiliated Hospital of Guangzhou Medical University between April 17 and September 25, 2023. HRQoL of the participants was assessed at 16-24 weeks of gestation, between 32 weeks and delivery, and 5-13 weeks postpartum. Mixed linear models were used for evaluating temporal trends of HRQoL changes, and univariate ANOVA with multiple linear regression was used to identify the predictors of HRQoL. RESULTS: Compared with healthy pregnant women, HBV-infected pregnant women had consistently lower total HRQoL scores across all the 3 intervals, with the lowest scores observed between 32 weeks of gestation and delivery, during which these women had significantly reduced mental component scores (74.27±13.43 vs 80.21±12.9, P=0.009) and postpartum mental (76.52±16.19 vs 85.02±6.51, P<0.001) and physical component scale scores (77.17±14.71 vs 83.09±10.1, P=0.009). HBV infection was identified as an independent risk factor affecting HRQoL during late pregnancy and postpartum periods. Additional independent risk factors for postpartum HRQoL reduction included self-pay medical expenses, spouse's neutral attitude toward the current pregnancy, and preexisting comorbidities (all P<0.05). CONCLUSIONS HRQoL of pregnant women deteriorates progressively in late pregnancy, and HBV infection exacerbates reductions of physical function and role emotion in late pregnancy and after delivery, suggesting the importance of targeted interventions for financial burdens, partner support and comorbid conditions to improve HRQoL of pregnant women with HBV infection.

Based upon the underlying mechanism and pathological evidence of tissue injury of antibody-mediated rejection (AMR) , four etiological and symptomatic therapies were proposed for managing AMR, including etiological treatment of AMR including antibody-targeting, B cell or plasma cell-targeting therapies; strategies for preventing antibody-mediated endothelial damage: an inhibition of complement/antibody dependent cell-mediated pathways; anticoagulant & thrombolytic therapies for thrombotic microangiopathy secondary to endothelial damage ; anti-inflammatory therapies for acute/chronic vascular inflammation secondary to endothelial damage. Etiological treatment is essential for preventing and treating AMR while symptomatic measures, such as anticoagulant, thrombolytic and antiinflammatory therapies, are stressed. Finally the authors devised therapeutic strategies for AMR in 4 different patient groups of non-sensitized allograft recipients, sensitized allograft recipients, individuals with active AMR and those with chronic active AMR.

Pancreatic cancer is a common malignant tumor in the digestive tract, and the difficulty of early diagnosis and the lack of effective treatment means are the main reasons for the poor prognosis of pancreatic cancer. In recent years, multidisciplinary treatment (MDT) has become an important means to break through the bottleneck of diagnosis and treatment of pancreatic cancer and improve clinical prognosis. Besides providing patients with high-quality diagnosis and treatment services, this treatment model helps to improve the clinical diagnosis and treatment level of specialists and cultivate high-quality compound medical talents. It also highlights clinical research groups and high-quality case resource sharing, and promotes the clinical application of innovative drugs and new diagnostic and therapeutic technologies, which plays an essential role in increasing the core competence of hospitals. This paper reviews and summarizes the origin, status quo, and deficiencies of the MDT diagnosis and treatment model of pancreatic cancer in China, and examines the prospects for future development, with the aim to provide reference for domestic and foreign counterparts.

Objective:To establish and verify a diagnostic model for distinguishing multiple sclerosis (MS) from other neurological diseases with similar symptoms by usingcerebrospinal fluid oligoclonal band (CSF-OCB)combined with IgG intrathecal synthesis indicators and biochemical markers.Methods:Multiple sclerosis (MS) patients admitted to the Neurology Department of Beijing Tiantan Hospital affiliated with Capital Medical University from January 2014 to December 2022 were selected as the case group, while patients with similar neurological symptoms were selected as the control group. Using the case-control study design, a retrospective analysis was conducted on the detection of age, gender, oligoclonal bands in cerebrospinal fluid, IgG intrathecal synthesis indicators and biochemical indicators for all study subjects. The differential diagnosis model was determined by the multiple logistic regression analysis, and the receiver operating characteristic (ROC) curve was used to analyze the diagnostic efficiency of the differential diagnosis model for neurological diseases with similar symptoms to MS and other conditions.Results:This study included 167 patients in the case group and 335 patients in the control group, of which 128 patients in the case group and 265 patients in the control group were used to construct the model, and 39 patients in the case group and 70 patients in the control group were used for model validation. The differential diagnostic model constructed by a multivariate logistic regression model was Y=0.871×CSF-OCB-0.051×CSFprotein-0.231×CSFchloride+1.183×gender-0.036×LDH+35.770. The model showed that the area under the curve, sensitivity and specificity were respectively 0.916, 87.3% and 87.6%. The Delong test results showed that the diagnostic efficacy of the model was significantly different from OCB, IgG intrathecal synthesis indicators, and OCB combined with IgG intrathecal synthesis indicators ( P<0.05). The new model validation showed that the actual diagnostic consistency rate for the MS group was 84.6%, while the actual diagnostic consistency rate for the control group was 90.0%. Conclusion:This study combines OCB, IgG intrathecal synthesis indicators, and biochemical indicators to establish a diagnostic prediction model for neurological diseases with similar clinical symptoms in MS. This model may have good differential diagnostic value and can better assist clinical diagnosis in the early stages of disease progression in MS patients.

Objective To investigate the safety and efficacy of Remimazolam combined with nalbuphine in painless endoscopic mucosal resection(EMR)of colorectal polyps.Methods A total of 100 patients who undergo painless colorectal polyp EMR were randomly divided into nalbuphine combined with remimazolam(NR)and nalbuphine combined with propofol(NP),with 50 patients in each group.The mean arterial pressure,heart rate and oxygen saturation were recorded after entry(T0),1min after administration(T1),1min at the beginning of surgery(T2),3min(T3),5min(T4),and at the end of surgery(T5).The frequency of application of vasoactive drugs,their operation time,consciousness vanishing time,recovery time,the times of supplementary sedation,dosage of incidence of nalbuphine,adverse reactions,The satisfaction of doctors and patients were compared.Results The mean arterial pressure of T1,T2,T3,T4 and T5 in the NR group was higher than that in the NP group(P<0.05),and the heart rate of T1 in the NR group was higher than that in the NP group(P<0.05).The incidence of respiratory depression,hypotension,injection pain,the recovery time and the frequency of application of vasoactive drugs in the NR group was lower than that in the NP group(P<0.05).The satisfaction of doctors in the NR group was higher than that in the NP group(P<0.05).There was no significant difference between the two groups in the operation time,oxygen saturation,the times of supplementary sedation,the dosage of incidence of nalbuphineincidence of dizziness,nausea and vomiting,and other adverse reactions(P>0.05).Conclusion Nalbuphine combined with remimazolam can be used safely in the EMR,has few perioperative adverse effects,and is a good choice for painless EMR.

Objective To analyze the effect of additional surgery on the survival and prognosis of high-risk T1 colorectal cancer patients who have undergone endoscopic resection.Methods The clinical data of patients with high-risk T1 colorectal cancer were retrospectively collected.The patients were divided into the endoscopic resection(ER)plus additional surgical resection(SR)group,or the ER+SR group,and the ER group according to whether additional SR were performed after ER.Baseline data of the patients and information on the location,size,and postoperative pathology of the lesions were collected.Patient survival-related information was obtained through the medical record system and patient follow-up.The primary outcome indicators were the overall survival and the colorectal cancer-specific survival.Univariate Cox regression analysis was used to screen survival-related risk factors and hazard ratio(HR)was calculated.Multivariate Cox regression analysis was used to analyze the independent influencing factors.Results The data of 109 patients with T1 high-risk colorectal cancer were collected,with 52 patients in the ER group and 57 patients in the ER+SR group.The mean age of patients in the ER group was higher than that in the ER+SR group(65.21 years old vs.60.54 years old,P=0.035),and the median endoscopic measurement of the size of lesions in the ER group was slightly lower than that in the ER+SR group(2.00 cm vs.2.50 cm,P=0.026).The median follow-up time was 30.00 months,with the maximum follow-up time being 119 months,in the ER+SR group and there were 4 patients deaths,including one colorectal cancer-related death.Whereas the median follow-up time in the ER group was 28.50 months,with the maximum follow-up time being 78.00 months,and there were 4 patient deaths,including one caused by colorectal cancer.The overall 5-year cumulative survival rates in the ER+SR group and the ER group were 94.44%and 81.65%,respectively,and the cancer-specific 5-year cumulative survival rates in the ER+SR group and the ER group were 97.18%and 98.06%,respectively.The Kaplan-Meier analysis showed no significant difference in the overall cumulative survival or cancer-specific cumulative survival between the ER+SR and the ER groups.Univariate Cox regression analysis showed that age and the number of reviews were the risk factors of overall survival(HR=1.16 and HR=0.27,respectively),with age identified as an independent risk factor of overall survival in the multivariate Cox regression analysis(HR=1.10,P=0.045).Conclusion For T1 colorectal cancer patients with high risk factors after ER,factors such as patient age and their personal treatment decisions should not be overlooked.In clinical practice,additional caution should be exercised in decision-making concerning additional surgery.

Objective To explore whether remote ischemic preconditioning(RIPC)can prolong the time of ultra-intense exercise(110%VO2max)by increasing the maximum cumulative oxygen deficit(MA-OD),and the specific ways of energy supply of the anaerobic metabolic system.Methods Twenty-four racquet athletes(22.2±2.0 years;174±9 cm;67.1±12.4 kg)completed three supramaximal intensi-ty tests on a treadmill at 110%VO2max intensity to exhaustion separated with Control,Placebo and RIPC interventions.RIPC was induced on the limbs on both sides(5×5 min alternating bilateral occlu-sion 220 and 60 mmHg for Placebo and RIPC interventions,respectively).Moreover,all groups under-went a fourth test with incremental load,and a fifth test with constant load at 40%,50%,60%,70%and 80%VO2max.Results The time to exhaustion and the MAOD of the RIPC group were both greater than those in the Placebo and Control groups(P<0.05).However,no significant differences were found in the average alternative maximal accumulated oxygen deficit(MAODALT),lactic anaerobic metabolism,alactic anaerobic metabolism and parameters of excess post-exercise oxygen consump-tion dynamic curve of the three groups(P>0.05).Meanwhile,in the RIPC group,the average MAOD was significantly higher than MAODALT(P<0.05).Pearson correlation analysis showed a significant rela-tionship between the improvement of MAOD and an increase in exhaustion time after RIPC interven-tion.Conclusion RIPC can improve supramaximal exercise performance of racquet athletes by enhanc-ing their MAOD,and the enhancement of glycolysis energy supply and lactic acid elimination is a po-tential intermediary of the improvement of sports performance.

Pharmacoeconomic evaluation is the essential supporting information for the inclusion of rare disease drugs into medical insurance in China. The accurate measurement of the health state utility of rare diseas is of practical significance to the development of rare disease pharmacoeconomic evaluation. Based on the review of pharmacoeconomic evaluation requirements for rare diseases in some countries/regions, we systematically retrieved the published studies on the measurement of health state utility for 121 rare diseases in China and other countries and regions. We identified 17 591 papers in the initial review, and later selected 230 after screening. We also made a comprehensive analysis of the quality of literature, evaluation content and use of tools for measuring health state utility in rare diseases in China. Finally, we analyzed the challenges in measurement in terms of population, instruments use, and application of results and made recommendations based on analysis, hoping to provide reference for the development of rare disease health state utility measurement studies in China.

Bone defects caused by different causes such as trauma, severe bone infection and other factors are common in clinic and difficult to treat. Usually, bone substitutes are required for repair. Current bone grafting materials used clinically include autologous bones, allogeneic bones, xenografts, and synthetic materials, etc. Other than autologous bones, the major hurdles of rest bone grafts have various degrees of poor biological activity and lack of active ingredients to provide osteogenic impetus. Bone marrow contains various components such as stem cells and bioactive factors, which are contributive to osteogenesis. In response, the technique of bone marrow enrichment, based on the efficient utilization of components within bone marrow, has been risen, aiming to extract osteogenic cells and factors from bone marrow of patients and incorporate them into 3D scaffolds for fabricating bone grafts with high osteoinductivity. However, the scientific guidance and application specification are lacked with regard to the clinical scope, approach, safety and effectiveness. In this context, under the organization of Chinese Orthopedic Association, the Expert consensus for the clinical application of autologous bone marrow enrichment technique for bone repair ( version 2023) is formulated based on the evidence-based medicine. The consensus covers the topics of the characteristics, range of application, safety and application notes of the technique of autologous bone marrow enrichment and proposes corresponding recommendations, hoping to provide better guidance for clinical practice of the technique.
